[0076] S16. Compare the target road matching index with a preset target road matching threshold. If the threshold comparison result does not meet the preset threshold comparison requirement, issue an alarm to remind the mobile target to adjust the road.

[0077] It should be noted that the laser monitoring platform is a platform that integrates various types of laser scanners to monitor the information of mobile targets. In order to realize automatic inspection of mobile targets based on laser scanners, thereby completing automatic inspection of mobile targets, especially high-speed moving targets, and ensuring that mobile targets comply with traffic rules without interrupting traffic, the technology first collects the initial point cloud information of the mobile target and extracts data to obtain the feature data of the mobile target, including the shape size data, thermal imaging feature data and audio feature data of the mobile target, and screens out the marked mobile targets through threshold comparison, obtains meteorological data and environmental data, and performs meteorological environment complexity assessment to obtain the meteorological environment interference index; obtains the feature data of the marked mobile target, and obtains the target characteristic recognition index in combination with the meteorological environment interference index, processes the road surface attribute data in combination with the road surface characteristic data, obtains the road attribute calibration index, and further performs compliance assessment in combination with the target characteristic recognition index to obtain the target road matching index; compares the marked road matching index with the threshold, and issues an alarm for those that do not meet the threshold comparison requirements, reminding the mobile target to adjust the road it is on.

[0078] Please refer to Figure 2 , Figure 2 The flowchart of the method for automatically inspecting mobile targets based on a laser scanner in some embodiments of the present application is to screen out and mark mobile targets. According to the embodiment of the present invention, the initial point cloud information of the mobile target is collected by a preset laser monitoring platform, and the initial point cloud information is extracted to obtain the feature data of the mobile target, including the shape size data, thermal imaging feature data and audio feature data of the mobile target, and the mobile target is screened out and marked by threshold comparison, including:

[0083] S25. If the three items of the characteristic data are all greater than the corresponding thresholds of the preset condition threshold set, the moving target is marked as a marked moving target.

[0084] It should be noted that before conducting a comprehensive and efficient automatic inspection of mobile targets, in order to improve accuracy, it is necessary to first screen the mobile targets to remove mobile targets that do not meet the preset requirements. First, three feature data of the mobile targets are obtained through existing multiple types of laser scanners, including shape dimension data, thermal imaging feature data and audio feature data, and compared with the existing corresponding preset thresholds. If these three feature data are all greater than the corresponding preset thresholds, then the mobile target will be marked as a marked mobile target and undergo the next stage of comprehensive monitoring and inspection.

[0087] S32, performing a meteorological environment complexity assessment based on the temperature data, precipitation data, wind speed data, and sunshine intensity data in combination with the air quality data and noise data to obtain a meteorological environment interference index;

[0091] It should be noted that the automatic inspection of mobile targets will be affected by environmental and meteorological interference, especially when the marked mobile targets are in complex environments and severe weather conditions. In order to improve the accuracy of automatic inspection and ensure the efficiency of inspection, it is necessary to fully consider the interference factors of the meteorological environment. Therefore, it is necessary to obtain the meteorological data and environmental data of the area where the marked mobile targets are located through the existing meteorological environment data monitoring platform database, and obtain the meteorological environment interference index through meteorological environment complexity assessment.

[0092] Please refer to Figure 4 , Figure 4 The present invention is a flowchart of obtaining a target characteristic recognition index based on a method for automatically inspecting a moving target using a laser scanner in some embodiments of the present invention. According to an embodiment of the present invention, the step of obtaining the characteristic data of the marked moving target and evaluating the target recognition degree based on the characteristic data in combination with the meteorological environment interference index to obtain the target characteristic recognition index includes:

[0093] S41, acquiring characteristic data of the marked moving target through a preset laser scanning data monitoring platform database, including target size data, target moving speed data, target moving direction data, target reflection intensity data, and target reflectivity data;

[0098] It should be noted that moving targets on the road can be divided into many types. Different types of moving targets have different characteristics. In order to identify the category characteristics of the marked moving targets, the characteristic data of the marked moving targets are first obtained through the existing laser scanning data monitoring platform database, including target size data, target moving speed data, target moving direction data, target reflection intensity data and target reflectivity data. Then, the target recognition degree is evaluated in combination with the meteorological environment interference index to obtain the target characteristic recognition index.

[0099] According to an embodiment of the present invention, the step of acquiring the pavement attribute data and pavement feature data of the road where the marked moving target is located, and performing processing according to the pavement attribute data in combination with the pavement feature data to obtain a road attribute calibration index of the road includes:

[0100] Acquire the pavement attribute data and pavement characteristic data of the road where the marked moving target is located through a preset road characteristic monitoring platform database;

[0101] Pavement attribute data include pavement type data, pavement age data, and pavement traffic flow data;

[0102] The pavement characteristic data includes pavement geometric characteristic data and pavement bearing capacity characteristic data;

[0103] The road attribute data is combined with the road feature data and processed through a preset road attribute evaluation model to obtain a road attribute calibration index for the road.

[0104] It should be noted that roads have different attributes. For example, highways have fast lanes, slow lanes and shoulders, and national highways have bus lanes. In order to identify the attributes of the road where the marked moving target is located, the pavement attribute data and pavement feature data of the road where the marked moving target is located are first obtained through the existing road characteristic monitoring platform database, and then the above data are input into the existing road attribute evaluation model for processing to obtain the road attribute calibration index of the road. Among them, the road attribute evaluation model is a neural network model. The initialized road attribute evaluation model is trained according to a large amount of historical pavement attribute data and pavement feature data to obtain a trained road attribute evaluation model.

[0105] According to an embodiment of the present invention, the target road conformity evaluation is performed according to the target characteristic recognition index in combination with the road attribute calibration index to obtain the target road matching index, including:

[0106] According to the target characteristic recognition index and the road attribute calibration index, a target road conformity evaluation is performed through a preset road matching evaluation model to obtain a target road matching index;

[0107] The calculation formula of the target road matching index is:

[0108] ;

[0109] in, is the target road matching index, , They are target feature recognition index and road attribute calibration index respectively. , is the preset characteristic coefficient. (The characteristic coefficient is obtained by querying the preset laser scanning monitoring platform database).

[0110] It should be noted that after obtaining the target characteristic recognition index of the marked mobile target and the corresponding road attribute calibration index, it is necessary to further determine whether the road on which the marked mobile target is located meets the requirements of traffic regulations. Therefore, it is necessary to evaluate the target road conformity based on the target characteristic recognition index of the marked mobile target and the road attribute calibration index through the calculation formula of the existing road matching evaluation model to obtain the target road matching index.

[0111] According to an embodiment of the present invention, the method further includes:

[0112] Obtaining a road attribute calibration index of the road where the marked moving target is located;

[0113] Determining whether the road classification index is within a preset parking prohibition calibration threshold range;

[0114] If so, determining whether the target characteristic recognition index of the marked moving target is within a preset special characteristic threshold range;

[0115] If not, obtaining the motion state information of the marked moving target, and determining whether the motion state information is within a first preset state threshold interval;

[0116] If it is, obtain the time data corresponding to the motion state information, compare the time data with a preset time threshold, and if the comparison result does not meet the preset range, issue an alarm to remind the marked moving target to leave the road.

[0117] It should be noted that when it is identified that the road where the marked moving target is located is a no-parking road, such as the exit of a fire passage, it is determined whether the moving target is a special target, such as an ambulance, fire truck or police car. If not, the motion state information of the moving target is further determined. When the motion state is in the first preset state threshold interval, this embodiment takes the threshold interval as 0-0.2, and starts to calculate the time data of the moving target on the no-parking road. When the time data exceeds the preset threshold, an alarm is issued to remind the marked moving target to leave the road.

[0118] According to an embodiment of the present invention, the method further includes:

[0119] Collecting monitoring information of the marked moving target, including speed information, position information, shape information and contour information;

[0120] Extracting characteristic data according to the monitoring information, including velocity change rate data, acceleration change rate data, direction change rate data, and target profile change amount data;

[0122] Comparing the target condition deviation index with a preset target condition matching threshold, if the threshold comparison result does not meet the preset threshold comparison requirement, issuing an alarm to remind the rescue center to perform road rescue for the marked moving target;

[0123] The calculation formula of the target condition deviation index is:

[0124] ;

[0125] in, is the target status deviation index, , , , They are velocity change rate data, acceleration change rate data, direction change rate data, and target profile change data. , , , is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset laser scanning monitoring platform database).

[0126] It should be noted that when an abnormal situation occurs in a moving target, such as a traffic accident, it is necessary to promptly report the situation and implement road rescue. At this time, the speed, acceleration, movement direction and external contour of the moving target may change abnormally. Therefore, it is necessary to collect monitoring information of the marked moving target, including speed, position, shape and contour information, and extract feature data, including speed change rate, acceleration change rate, direction change rate and target contour change amount. Deviation evaluation is performed based on the above feature data to obtain the target condition deviation index of the marked moving target, and at the same time, it is compared with the preset target condition matching threshold to obtain the comparison result, and corresponding processing is performed based on the comparison result.

[0132] According to the target characteristic recognition index and the road attribute calibration index, the target road conformity evaluation is performed to obtain the target road matching index;

[0133] The target road matching index is compared with a preset target road matching threshold. If the threshold comparison result does not meet the preset threshold comparison requirement, an alarm is issued to remind the mobile target to adjust the road it is on.

[0134] It should be noted that the laser monitoring platform is a platform that integrates various types of laser scanners to monitor the information of mobile targets. In order to realize automatic inspection of mobile targets based on laser scanners, thereby completing automatic inspection of mobile targets, especially high-speed moving targets, and ensuring that mobile targets comply with traffic rules without interrupting traffic, the technology first collects the initial point cloud information of the mobile target and extracts data to obtain the feature data of the mobile target, including the shape size data, thermal imaging feature data and audio feature data of the mobile target, and screens out the marked mobile targets through threshold comparison, obtains meteorological data and environmental data, and performs meteorological environment complexity assessment to obtain the meteorological environment interference index; obtains the feature data of the marked mobile target, and obtains the target characteristic recognition index in combination with the meteorological environment interference index, processes the road surface attribute data in combination with the road surface characteristic data, obtains the road attribute calibration index, and further performs compliance assessment in combination with the target characteristic recognition index to obtain the target road matching index; compares the marked road matching index with the threshold, and issues an alarm for those that do not meet the threshold comparison requirements, reminding the mobile target to adjust the road it is on.

[0135] According to an embodiment of the present invention, the initial point cloud information of the mobile target is collected by a preset laser monitoring platform, and data is extracted from the initial point cloud information to obtain feature data of the mobile target, including the shape size data, thermal imaging feature data and audio feature data of the mobile target, and the mobile target is marked by screening out the threshold comparison, including:

[0136] Collecting initial point cloud information of the moving target through a preset laser monitoring platform, including initial spatial coordinate information, initial timestamp information, initial normal vector information, initial point cloud density information, initial temperature value information and initial audio signal information;

[0137] Processing the initial point cloud information through a preset mobile target feature description model to obtain feature data of the mobile target, including shape dimension data, thermal imaging feature data, and audio feature data;

[0138] Acquire a preset condition threshold set of the mobile target, wherein the preset condition threshold set includes a preset size threshold, a preset thermal imaging feature threshold, and a preset audio feature threshold;

[0139] Compare the characteristic data with the three thresholds of the preset condition threshold set;

[0140] If the three items of the characteristic data are all greater than the corresponding thresholds of the preset condition threshold set, the moving target is marked as a marked moving target.

[0141] It should be noted that before conducting a comprehensive and efficient automatic inspection of mobile targets, in order to improve accuracy, it is necessary to first screen the mobile targets to remove mobile targets that do not meet the preset requirements. First, three feature data of the mobile targets are obtained through existing multiple types of laser scanners, including shape dimension data, thermal imaging feature data and audio feature data, and compared with the existing corresponding preset thresholds. If these three feature data are all greater than the corresponding preset thresholds, then the mobile target will be marked as a marked mobile target and undergo the next stage of comprehensive monitoring and inspection.

[0142] According to an embodiment of the present invention, the step of acquiring meteorological data and environmental data of the area where the marked mobile target is located, performing a meteorological environment complexity assessment based on the meteorological data and environmental data, and obtaining a meteorological environment interference index includes:

[0143] Acquire meteorological data and environmental data of the area where the marked mobile target is located through a preset meteorological and environmental data monitoring platform database, wherein the meteorological data includes temperature data, precipitation data, wind speed data, and sunshine intensity data, and the environmental data includes air quality data and noise data;

[0144] According to the temperature data, precipitation data, wind speed data and sunshine intensity data, combined with the air quality data and noise data, the meteorological environment complexity assessment is performed to obtain a meteorological environment interference index;

[0145] The calculation formula of the meteorological environment interference index is:

[0148] It should be noted that the automatic inspection of mobile targets will be affected by environmental and meteorological interference, especially when the marked mobile targets are in complex environments and severe weather conditions. In order to improve the accuracy of automatic inspection and ensure the efficiency of inspection, it is necessary to fully consider the interference factors of the meteorological environment. Therefore, it is necessary to obtain the meteorological data and environmental data of the area where the marked mobile targets are located through the existing meteorological environment data monitoring platform database, and obtain the meteorological environment interference index through meteorological environment complexity assessment.

[0149] According to an embodiment of the present invention, the step of acquiring the characteristic data of the marked mobile target and evaluating the target recognition degree according to the characteristic data in combination with the meteorological environment interference index to obtain the target characteristic recognition index includes:

[0150] Acquiring characteristic data of the marked moving target through a preset laser scanning data monitoring platform database, including target size data, target moving speed data, target moving direction data, target reflection intensity data, and target reflectivity data;

[0155] It should be noted that moving targets on the road can be divided into many types. Different types of moving targets have different characteristics. In order to identify the category characteristics of the marked moving targets, the characteristic data of the marked moving targets are first obtained through the existing laser scanning data monitoring platform database, including target size data, target moving speed data, target moving direction data, target reflection intensity data and target reflectivity data. Then, the target recognition degree is evaluated in combination with the meteorological environment interference index to obtain the target characteristic recognition index.

[0156] According to an embodiment of the present invention, the step of acquiring the pavement attribute data and pavement feature data of the road where the marked moving target is located, and performing processing according to the pavement attribute data in combination with the pavement feature data to obtain a road attribute calibration index of the road includes:

[0157] Acquire the pavement attribute data and pavement characteristic data of the road where the marked moving target is located through a preset road characteristic monitoring platform database;

[0158] Pavement attribute data include pavement type data, pavement age data, and pavement traffic flow data;

[0159] The pavement characteristic data includes pavement geometric characteristic data and pavement bearing capacity characteristic data;

[0160] The road attribute data is combined with the road feature data and processed through a preset road attribute evaluation model to obtain a road attribute calibration index for the road.

[0161] It should be noted that roads have different attributes. For example, highways have fast lanes, slow lanes and shoulders, and national highways have bus lanes. In order to identify the attributes of the road where the marked moving target is located, the pavement attribute data and pavement feature data of the road where the marked moving target is located are first obtained through the existing road characteristic monitoring platform database, and then the above data are input into the existing road attribute evaluation model for processing to obtain the road attribute calibration index of the road. Among them, the road attribute evaluation model is a neural network model. The initialized road attribute evaluation model is trained according to a large amount of historical pavement attribute data and pavement feature data to obtain a trained road attribute evaluation model.

[0162] According to an embodiment of the present invention, the target road conformity evaluation is performed according to the target characteristic recognition index in combination with the road attribute calibration index to obtain the target road matching index, including:

[0163] According to the target characteristic recognition index and the road attribute calibration index, a target road conformity evaluation is performed through a preset road matching evaluation model to obtain a target road matching index;

[0164] The calculation formula of the target road matching index is:

[0165] ;

[0166] in, is the target road matching index, , They are target feature recognition index and road attribute calibration index respectively. , is the preset characteristic coefficient. (The characteristic coefficient is obtained by querying the preset laser scanning monitoring platform database).

[0167] It should be noted that after obtaining the target characteristic recognition index of the marked mobile target and the corresponding road attribute calibration index, it is necessary to further determine whether the road on which the marked mobile target is located meets the requirements of traffic regulations. Therefore, it is necessary to evaluate the target road conformity based on the target characteristic recognition index of the marked mobile target and the road attribute calibration index through the calculation formula of the existing road matching evaluation model to obtain the target road matching index.

[0168] According to an embodiment of the present invention, the method further includes:

[0170] Determining whether the road classification index is within a preset parking prohibition calibration threshold range;

[0171] If so, determining whether the target characteristic recognition index of the marked moving target is within a preset special characteristic threshold range;

[0172] If not, obtaining the motion state information of the marked moving target, and determining whether the motion state information is within a first preset state threshold interval;

[0173] If it is, obtain the time data corresponding to the motion state information, compare the time data with a preset time threshold, and if the comparison result does not meet the preset range, issue an alarm to remind the marked moving target to leave the road.

[0174] It should be noted that when it is identified that the road where the marked moving target is located is a no-parking road, such as the exit of a fire passage, it is determined whether the moving target is a special target, such as an ambulance, fire truck or police car. If not, the motion state information of the moving target is further determined. When the motion state is in the first preset state threshold interval, this embodiment takes the threshold interval as 0-0.2, and starts to calculate the time data of the moving target on the no-parking road. When the time data exceeds the preset threshold, an alarm is issued to remind the marked moving target to leave the road.

[0179] Comparing the target condition deviation index with a preset target condition matching threshold, if the threshold comparison result does not meet the preset threshold comparison requirement, issuing an alarm to remind the rescue center to perform road rescue for the marked moving target;

[0180] The calculation formula of the target condition deviation index is:

[0183] It should be noted that when an abnormal situation occurs in a moving target, such as a traffic accident, it is necessary to promptly report the situation and implement road rescue. At this time, the speed, acceleration, movement direction and external contour of the moving target may change abnormally. Therefore, it is necessary to collect monitoring information of the marked moving target, including speed, position, shape and contour information, and extract feature data, including speed change rate, acceleration change rate, direction change rate and target contour change amount. Deviation evaluation is performed based on the above feature data to obtain the target condition deviation index of the marked moving target, and at the same time, it is compared with the preset target condition matching threshold to obtain the comparison result, and corresponding processing is performed based on the comparison result.
